Abstract	60 GHz wireless personal area networks (WPANs) are bringing a new wave of high data rate applications because they promise multi-Gbps level communications. This paper exploits the spatial reuse of location information aided 60 GHz multi- user beamforming systems. When the location information is available at the network coordinator, the scheduler chooses a set of maximum angularly separated links to share the same time slot simultaneously. If additional feedback of signal-to- interference and noise ratio (SINR) is known, a location-assisted scheduler is employed to increase the system overall performance. The position error sensitivity is also discussed. The results show that significant enhancement can be achieved by the proposed schedulers for 60 GHz WPAN systems and we observe an accuracy of 98% compared with the error free transmission with ultra-wideband (UWB) localization systems.
